'An object oi the invention is to provide a pressure'mem-' berwithin the channel adapted to exert pressure on the edge of the window sash to yieldingl'y retain it against looseness and rattling, while at thesametime-permitting it to be easily raised and lowered, and further'toprovide in combination with such pressure member a rack and lock ing means with which the sash lock of the win- I, dow is adapted'to cooperate. Anotherobjectis;

to provide a pressure member having locking or the sash lock in such closed. position, to the end that the pressure member will-remai.n"-in uniform pressure exerting relation'w ith'the edge of the window throughout its length, thereby in; suring an effective weather seal and cushion s'supportfor the windoW-inthe closed position'of the window; when such Weather seal and support-is,

most desirable.

section and comprises-an outsidestopoi generally a recess l9 at its inner side, the inside stop 20 adapted to be engaged over this flange l8 and within the recess L! to complete the channel, the inside stop being provided with an offset flange portion 2| which embraces the. outer side of the flange I8. The particular construction of the outside and inside stops constituting the side channel form no part of the present invention, and it will be unde'rstood that any suitable construction may be employed.

A channel strip 22 is disposed within the side channel and has its forward edges bent inwardly, as at 2323, to engage the facing material 5, these edges being spaced apart to provide a vertical slot through which the sash lock plunger l 0 projects and is adapted to have vertical movement as the window is raised and lowered. A pres sure spring is secured to the rear side of the channel strip and comprises a right angular base portion 24, spot-welded or otherwise suitably secured to the rear face and one side face of the channel strip, ,an intermediate spring leaf portion 25 bent from one vertical edge of said base, and a spring leaf. abutment portion 25 bent back from the edge of the spring leaf portion 25, this spring leaf portion 26 preferably having a convex engaging surface 21 for engaging the base of. the side channel. In the assembled relation this spring is compressed between the base ll of the side channel and baseof the channel strip 22 and presses the latter-inwardly against the facing material 5 to yieldingly retain the edge of the window sash against looseness and rattling and at the same time permit it to be easily raised and lowered. The spring member extends from a point immediately above the upper edge of the sashlock plunger to the top of the channel strip. It will be'understood that other suitable types of spring means than that illustrated may be employed, if desired.

Within the base of the channel strip there is provided a'slot 28 in line with. the sash lock plunger Ill inthe closed position of the window sash and within which the plunger engages in such closed position. A rack member 29 is 'secured to the inner faceof the base of the channel member; as by spot-Welding, riveting or other suitable means, and extends from a point imme-' diately above the slot 28 to a point along the channel member sufficiently high to engage the sash lock plunger at the maximum raise of the window sash.

In the closedposition of the window sash it will be seen that the engagement of the plunger l0 with the slot 28 provides a locking means for the window which will prevent it from being.

raised, except by retraction of the plunger through-operation of the operating member II. In this position the side channel .member is entirely relieved of the pressure of the. sash lock plunger, so thatthere is no. tendency for the channel member to be pressed away from the facing material 5 at its lower end, as would be the case if the plunger pressed upon the channel member. The channel member spring is therefor permitted to uniformly press the channel member against the facing material throughout its height, so that an even tight closure of the window' is maintained. The spring is also prevented from becoming unevenly set, as would be thecase if there was an uneven pressure applied to it forany considerable length of-time. Upon retraction of I the plunger the window sash may be raised, and the plunger thereupon ratchetsalong I the rack 29 and maybe retained at any point of and permits it to be easily raised and lowered.

It furthermore provides a convenient and automatic lock for'the closed position of the window and rack means for retaining the window at any desired open point. The rack is concealed and protected against the lodgement therein of dirt and extraneous mattenand a side channel is providedwhich is very compact and narrow in width and which provides maximum clear vision through the window. i

I have illustrated and described a preferred and satisfactory embodiment of the invention, but it will be obvious that changes may be made therein, Within the spirit and scope thereof, as defined in the appended claims. 7 Y
